Dan Henderson was supposed to fight in the co-main event of the UFC on FOX 19 card. Well, he’s not, and to say he’s unhappy about it would be an understatement. UFC on FOX 19 takes place in Tampa, Fla. on Saturday, and Henderson was already on site for the event when he was told that his opponent, Lyoto Machida was going to fail his drug test. On Wednesday the UFC confirmed that Machida was out of the fight, after Machida revealed that he had taken a banned substance ahead of the fight. With no replacement available on such short notice, Henderson will be moved to June’s UFC 199 event where he will fight Hector Lombard.
